Bayhorse Silver - XRF Analysis of Bayhorse Silver Mine Flotation Concentrate Samples Shows Significant Contained Silver/Copper/Antimony/Zinc

Vancouver, British Columbia--(Newsfile Corp. - October 20, 2025) - Bayhorse Silver Inc, (TSXV: BHS) (OTCQB: BHSIF) (FSE: 7KXN) (the "Company" or "Bayhorse") has conducted an XRF field analysis of the Bayhorse flotation concentrate samples from its silver-copper-antimony-zinc rich Bayhorse Silver Mine in Oregon, USA recently sent to Allihies Engineering Inc. ("Allihies"), Montana, for testing using Allihies's proprietary Antimony leaching technology.

A 20 kg sample was taken from three (3) locations within one seven (7) tonne (7.5 ton) flotation concentrate stockpile at the Bayhorse Mill, of which a 6.5 kg (14.3lb) sample was field tested using the Company's Sci-Aps "X" series X-Ray Flourescence Unit ("XRF") and separated into three (3) separate samples. One 5.5kg (12lb) was sent to Allihies, one 0.5 kg (1.1lb) sample was submitted to Paragon Laboratory for full metals analysis, including sulphur content, to compare to the XRF field analysis, and one reference 0.5 kg sample that is kept at the Bayhorse Mill.

Four XRF field analyses measurements were taken of the 6.5 kg samples in order to get a representative analysis and are reported in the table below.
